Studying memory narratives with natural language processing Cognitive neuroscience research has begun to use natural language processing (NLP) to examine memory narratives with the hopes of gaining a nuanced understanding of the mechanisms underlying differenc...

Quantifying memory recall is hard! Luckily, natural language processing (incl. #LLMs) offers new, automated, and scalable ways to do that!

Great new review by Fenerci & @signysheldon.bsky.social in @cp-trendscognsci.bsky.social!

Neural and behavioral reinstatement jointly reflect retrieval of narrative events - Nature Communications When people recall a movie, their eye movements and brain activity resemble those observed during the viewing. These behavioral and neural reactivations are linked through a common process, likely ref...

Excited to share our new paper w/ @cibaker.bsky.social in @natcomms.nature.com linking active vision & memory!

We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. doi.org/10.1038/s414...

Replay in the human visual cortex during brief task pauses is linked to implicit learning of successor representations | PNAS Humans can implicitly learn about multistep sequential relationships between events in the environment from their statistical co-occurrence. Theore...

Delighted to share our work on replay and successor representations! We find replay during very short task pauses in human visual cortex that is linked to learning SRs & happens when learning is implicit. Study led by @lnnrtwttkhn.bsky.social

New paper with @mujianing.bsky.social & @prestonlab.bsky.social! We propose a simple model for human memory of narratives: we uniformly sample incoming information at a constant rate. This explains behavioral data much better than variable-rate sampling triggered by event segmentation or surprisal.

The House committee for NSF/NASA/NOAA is meeting tomorrow (Tuesday) at noon ET. Now would be a good time to call anyone on this list & tell them to keep science funding at full 2025 levels. You can remind them that 75% of voters want tax-funded science and they're concerned about the impact of cuts.

Excited to share my new lab website!

The Learning & Behavior Change Lab will launch at Rice in July 2026. I’ll be recruiting over the next year! @ricesocsci.bsky.social

Music is an incredibly powerful retrieval cue. What is the neural basis of music-evoked memory reactivation? And how does this reactivation relate to later memory for the retrieved events? In our new study, we used Eternal Sunshine of the Spotless Mind to find out. www.biorxiv.org/content/10.1...

Pleased to say "Space, Time, and Memory", an academic book by Oxford University Press edited by the inimitable Lynn Nadel & Sara Aronowitz is now out.
I contributed a chapter, "Memory and Planning in Brains and Machines".

I just signed the Bethesda Declaration and urge you to do the same today, so that we all stand with NIH researchers as Battacharya appears before the Senate Appropriations Committee tomorrow.

‘A big win’: Dubious statistical results are becoming less common in psychology Fewer papers are reporting findings on the border of statistical significance, a potential marker of dodgy research practices

Thrilled to see a news piece by @science.org on my recent paper. By analyzing p-values across >240k papers, the study suggests that the rate of statistically questionable findings in psychology has declined since the replication crisis began

Congratulations, Q! Thoroughly deserved!

I’m thrilled to announce that I will start as a presidential assistant professor in Neuroscience at the City U of Hong Kong in Jan 2026!
I have RA, PhD, and postdoc positions available! Come work with me on neural network models + experiments on human memory!
RT appreciated!

Yes, that would be my default setting. But as I used the AI-agent over time it could become graded. I purchased your book based on an ad that I saw on your website, and I really enjoyed the book. So perhaps I would instruct my AI-agent to relay certain ad information but not others?

Presumably the AI-agent would still be able to view the ads and report back to their user if they came across something advertised which would be interesting/useful for their user.

I guess you are considering the case where the user explicitly tells the AI not to inform them of anything ad-related?

FINALLY.

Some gumption from the President of Harvard today:

All I can say is that the subjective effect size of the difference is very large and beyond what I would normally question. Once I start to question the validity of such judgments, I don't know how I could trust the majority of my waking self-report.

I've (on occasions) had normal waking imagery that is vivid. That waking imagery is just like the vivid imagery that I (much more often) experience near sleep. I agree that I'm always comparing two past states here, which involves some kind of memory function.

I am close to aphantasic (~2 out of 7 visual and auditory). However, there is an exception: I experience visual and auditory imagery when I am on the edge of sleep. So I know what imagery is, and I just don't experience it at other times. I don't know *how* I could be so wrong in subjective report.

Synaptic plasticity rules driving representational shifting in the hippocampus - Nature Neuroscience Madar et al. report that behavioral timescale synaptic plasticity (BTSP), not spike-timing-dependent plasticity, explains heterogeneous place fields shifting in the hippocampus. The probability of BTS...

BTSP, but not STDP, can account for place field changes in hippocampus, out in Nature Neuroscience today:

Science Under Threat in the United States: How scientists and institutions should respond Individual researchers and university leaders need to make the case for science to their elected representatives and to the public at large.

Science is under threat in the US. @elife.bsky.social have commissioned a series of articles discussing the implications and what we can do. The first three articles are now live. More to follow:

getting this paper published was a bit painful but I am proud of it: www.nature.com/articles/s41.... We use deep RL to find mechanisms that help (real) people sustain the commons. Well done to Raphael Koster and Miruna Pislar (not on BlueSky). non-paywalled version on arxiv.

fantastic post, and tasty food for thoughts.

shamelessly adding here that many different types of STDP come about from minimizing a prediction of the future loss function with spikes :)

hopefully another case of successful predictions.
